windows 7 - Toshiba Satellite P850 - Freezing and Stuttering

I've about exhausted all my known options at this point. I own a Toshiba Satellite p850 which was new in 2012. The laptop frequently (several times per minutes) locks up or stutters the entire system. The problem is consistent regardless of CPU, GPU, hard drive, or memory load. Even clocking at a low load on any of these things the problem will occur as frequently as during a high load. Below is the computer's hardware.
Intel i7 3rd generation processor, 2.4Gh standard and factory overclocked to 3.2Gh Nvidia GeForce 630m graphics processing unit 8Gb RAM 500 GB SATA drive at 7200 RPM
I've tried numerous solutions to attempt fixing the problem. This includes:
Scanning for malware using Malwarebytes AM and later AVG security. I also used a more extensive program to check for rootkit viruses. Defragmenting the hard drive, fixing registry errors, and checking for damage to the hard drive. Changing the computer and GPU settings to favor high power use and performance. A fresh install of windows.
One attempt had pretty interesting results. It was recommended that I disable intel Turbo Boost. I did so and the computer performed perfectly for about a day before returning to its state of hang ups and stuttering. I then re-enabled it and it performed perfectly for several more hours. Since then, no luck. I'm curious about that because it could point to the source of my computer troubles.

I have a Toshiba Satellite 1900-603 laptop that I'm trying to add memory to. It came with 512Mb RAM (which I was told consisted of 2x256Mb sticks) and after research I ordered two 512Mb sticks which arrived this morning.
The existing memory turned out to be on 1x512Mb stick and I replaced it with one of the new ones (which resulted in the computer now reporting it has 768Mb of RAM which is nice but puzzling).
Anyway, my question is where is the second memory slot? The one that was being used only takes 1 stick. There is a second slot in the same compartment (described as the memory module in the manual) but the second slot isn't wide enough to take the second stick nor does it have the 'notch' to show which way to install the memory.
Everything I've read from the manual to online states it has two memory slots so where is it? Any photos or videos showing the second slot would be particularly useful.
Thanks for any help...

Problem solved!
After a lot of searching, I found this walkthrough Although it's for a different model, physically it's identical to my Satellite 1900-603.
It turns out the second memory slot is under the keyboard - NOTHING I read before (including the manual) suggested this. Also, it turned out each slot originally came with 256Mb of memory installed which explains why, after I installed one 512Mb stick, Windows reported 768Mb of memory.
Anyway, after wrestling the plastic strip off and getting to the keyboard (Tip: try and shift the strip to the left a little first which releases the plastic 'teeth'), I've now installed the second stick and Windows shows 1Gb RAM is now installed.
